Mayor Levar Stoney announced the effort, dubbed “Richmond 300,” as an overhaul of the existing city master plan that’s meant to guide growth and development in the city over the next 20 years in the run-up to Richmond’s 300th birthday in 2037.”Providing a vision for the Master Plan update is an important first step,” Stoney said in a statement. “These open house events will help ensure every Richmonder has a say in how the city grows, and I encourage everyone to make an effort to attend.”
